/**
* Replace a content type in this package.
*
* <p>
* A typical scneario to call this method is to rename a template file to the main format, e.g.
* ".dotx" to ".docx"
* ".dotm" to ".docm"
* ".xltx" to ".xlsx"
* ".xltm" to ".xlsm"
* ".potx" to ".pptx"
* ".potm" to ".pptm"
* </p>
* For example, a code converting a .xlsm macro workbook to .xlsx would look as follows:
* <p>
* <pre><code>
*
* OPCPackage pkg = OPCPackage.open(new FileInputStream("macro-workbook.xlsm"));
* pkg.replaceContentType(
* "application/vnd.ms-excel.sheet.macroEnabled.main+xml",
* "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet.main+xml");
*
* FileOutputStream out = new FileOutputStream("workbook.xlsx");
* pkg.save(out);
* out.close();
*
* </code></pre>
* </p>
*
* @param oldContentType the content type to be replaced
* @param newContentType the replacement
* @return whether replacement was succesfull
* @since POI-3.8
